Ferrous metals mainly refer to iron, manganese, chromium and their alloys, and none of them are black. Pure iron is silvery white; chromium is silvery white; manganese is grayish white. Because the surface of iron is often rusted, it is covered with a mixture of black ferric oxide and brown iron oxide, which looks black. So people call it "black metal". Mining and beneficiation of ferrous metal ores refers to the mining and beneficiation of iron ore, manganese ore, chromium ore and other ferrous metal raw materials for the iron and steel industry. The main activity is iron ore mining and beneficiation.
